Apple now accepting preorders of iPhone XS, iPhone XS Max and Apple Watch Series 4 [u]

Similar to previous iPhone launches, preorders first went live on the dedicated Apple Store app for iOS, with Apple.com coming online shortly thereafter.

The stainless steel iPhone XS and XS Max are available in the same silver and Space Black finishes seen on last year's iPhone X, but Apple is adding a new gold hue to the palette for 2018. Aside from a larger 6.5-inch OLED display and battery on the XS Max, the two handsets feature a largely identical array of components.

Prices start at $999 for the iPhone XS with 64GB of storage and move up to $1,149 for 256GB model. This year's top-end 512GB version comes in at $1,349. The iPhone XS Max sells for $1,099 with 64GB of storage, $1,249 for 256GB and $1,449 for 512GB.

Apple is launching the flagship iPhones in 33 countries and territories including Australia, Austria, Belgium, Canada, China, Denmark, Finland, France, Germany, Guernsey, Hong Kong, Ireland, Isle of Man, Italy, Japan, Jersey, Luxembourg, Mexico, Netherlands, New Zealand, Norway, Portugal, Puerto Rico, Saudi Arabia, Singapore, Spain, Sweden, Switzerland, Taiwan, the UAE, UK, U.S. and U.S. Virgin Islands.
